MARKING ATTACHMENT FOR CARPENTERS PENCILS.

SPECIFICATION forming part of Letters Patent No. 486,513, dated November22, 1892.

Application filed October 5, 1891. Serial No. 407,698. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALBERT F. STREET, of Rockville, in the countyTolland and State of Connecticut, have invented certain new and usefulImprovements in Marking Attachments for Carpenters Pencils, of which thefollowing is a full, clear, and exact description, whereby any oneskilled in the art can make and use the same.

The object of my invention is to provide a carpenters pencil with anattachment by the use of which a tool is provided with a markingpointfor use in making a finer line for the marking off of distances than ispossible with the use of the lead or pencil end; and to this end myinvention consists in the combination of a carpenters or like flatpencil with a sliding sleeve borne on the pencil and provided with aflat projecting blade, as more particularly hereinafter described, andpointed out in the claims.

, adetail end view of the device.

Referring to the drawings, Figure l is a detail side View of acarpenters pencil provided with my improved marking attachment. Fig. 2is a detail top view of the same. Fig. 3 is Fig. 4 is a detail viewillustrating the manner of using the marker.

In the accompanying drawings, the letter a denotes a pencil such as iscommonly used by carpenters, having flat sides and being usually formedin cross-section to the shape of an irregular hexagon. On such a pencilis fitted a marker 1), formed of a sleevesection b and a blade b Thismarker is made of a sheet of metal of more or less resiliency and isusually stamped to shape from a fiat piece of thin metal and then foldedup to the required form of a sleeve that will adapt it to fit snugly onthe pencil and be held there by a frictional grasp of the walls of thesleeve. The metal is cut away, as at c, to lighten the sleeve and alsoto leave a portion d, that forms a spring that may be slightly depressedbelow the surface of the sleeve, so as to afford a surer frictionalgrasp upon the pencil to prevent the accidental sliding of the sleeve,and the sleeve may also be provided with one or more openings at variouspoints thereof, as shown in Figs. 2 and? of the drawings. These openingsalso afford holding means for the ready grasping of the pencil and themarker in using the same. This sleeve is formed, preferably, of steeland the blade I) is tempered and hardened and brought to the propersquare point to provide sharp marking-edges. WVhen not in use, thesleeve is arranged on the pencil with the blade lying against the sideand in from the end,-while when needed for use the sleeve is readilyslid toward the end of the pencil, so that the blade projects adistance, as shown in the several figures of the drawings, to enable itto be used, as shown in Fig. 4. The blade being flat narrow andsharp-pointed enables a mark denoting any distance or line to be veryaccurately marked.

This marking attachment is not only adapted to the flat pencildescribed,but to an oval one, the main requisite being that the pencilshall be of such shape and the marker so adapted as to prevent thelatter from rotating or slipping around on the pencil. The sleeve is soformed as to practically form spring grasping-arms extending both waysfrom that portion of the sleeve that is in line with the projectingblade, one end of the sleeve being cut away, as shown in figures of thedrawings, so as to provide for an extension of the blade beyond the endof the sleeve.

I claim as my invention- 1. In combination with a carpenters pencil flator oblong in cross'section, an adjustable sleeve conforming in shape tothe shape of the pencil and provided with frictional clamping-arms, anda projecting flat blade having an angular marking-point, allsubstantially as described.

2. In combination with a carpenters pencil fiat or oblong incross-section, an adjustable sleeve conforming in shape to the shape ofthe pencil and provided with frictional clamping-arms, a projecting flatblade having an angular marking-point, and the corrugations formed inthe body of the sleeve, all substantially as described.
